I left IPv6 disabled on the default interface , but noticed in ifconfig that eth0 had picked up an IPv6 address, so I disabled that: $ sudo sysctl net. ipv6 .conf.eth0.disable_ ipv6 =1 I also added that same line to /etc/sysctl. conf .
To dynamically enable ipv6 on an interface, use the commands given below. # sysctl net.ipv6.conf. [interface].disable_ipv6 = 0 ### put interface name here [interface], i.e, eth0 # sysctl net.ipv6.conf.default.disable_ipv6 = 0. 3. To dynamically enable ipv6 on.
6/16/2017 · sysctl: cannot stat /proc/sys/net/ipv6/conf/eth0/disable_ipv6: No such file or directory. So first step would be to enable ipv6 from GRUB. Delete the entry “ipv6.disable=1” from “GRUB_CMDLINE_LINUX” variable in /etc/default/grub. # grep.

For networks which uses Router Advertisements to set the IPv6 router/gateway RHEL presents a challenge if you want to configure a static IPv6 address and not having the autoconfigured IPv6 .
That makes sense. Merely removing the lines setting IPv6 to disabled didn’t actually do anything to re- enable it. $ sudo sysctl net. ipv6 .conf.all.disable_ ipv6 =0 net. ipv6 .conf.all.disable_ ipv6 = 0 $ sudo sysctl net. ipv6 .conf. lo .disable_ ipv6 =0 net. ipv6 .conf. lo .disable_ ipv6 = 0. After that change, ping6 ::1 and ping6 localhost worked as expected.
The sysctl variable stable_secret contains the secret for the generation of stable interface identifiers (normally the lower 64 bit in IPv6 addresses) as defined in RFC 7217, A Method for Generating Semantically Opaque Interface Identifiers with IPv6 Stateless Address Autoconfiguration (SLAAC).
